RADIATOR.

Application led January 21, 1922. Serial No. 530,768.

To all whom it may concern.'

Be it known that T, Taio. R. Sinzatiimtn, a citizen ot the United States of America, residing,r at Detroit, in the county of lVayne and State ot Michigan, havenvented certain new and useful Improvements in Radiators, of whichthe following is a specification, reference beine,r had therein to thx accompanying drawings. I

In the manufacture of automobile radiators wherein headers or top and bottom receptacles are connected by tubes, it is the present practice to aperture `or punch the bottom wall of the ripper header and the top wall of the lower'lliieader to receive the ends of the tubes. suchaperturug or punching providing out-struck material or flanges that may be. soldered or otherwise connected to the walls ot the tubes to all'ord non-leakable connections between the tubes and headers. The out-struck materials or ilanges are, in the majority ol instances, 'limited to the size ol "-.e apertures and since the tubes are small there is very little mate-fail. of sleeve like or lug formation, that may be scoured to the tubes. In consequence el'. this the joints between the tubes and headers ared weak, not always perfect. and ot such nature as to leak should the radiator receive a blow or be distorted. Repair is ,not always iossible and time and expense are incurre' in the maintenance ot industrial' triicls or vehicles provided with radiators.

, lily invention aiins to lirovide headers which will afford better tastcninif means and jointstor the tubes of a radiator, and re duce, it not completely eliminate, radiator repair. i My invention radiator headers with doable walls which :idd riggidit)vv tothe radiator core and entire radiator structure.

lily in'vcntii'in further aims to reinforcethe exposed portions ot a adiator core, which -are liable to ieceii'c blows, and thus strength-- .ou and increase the longevity of the radiator.

"l`he improvements will be hereinafter de scribed and then claimed. and i'e'lercijice will now be had to the drawing. wherein Figure l is a vertical V longitudiiial sectional view o'la radiator in :iccordai'ice with ',nrv invention.A and Fig. 2 is a plan oi" a double wall adapted to form part of the radiator header. jfor instance, the bottom wall of the upper head farther aims to provide' 'in spacedrelation when thermarginal-portions thereof are connected or Joined, as brought out in 1. `With the' marginal er. the view being laken on the line 2-2 ot' Fig.- l.

The radiator comprises a lower basin-like header or receptacle l which ordinarily has its end edges 2 supported from or by the side tl ot an automobile chassis, and this.

be wall.

ing the apertures 5 oirone face ot t Ll. Iii the sleeves Gare placed the lo' 'o`t tubes 7 andJ thesleeves (i are coiinected to the exterior walls of the tubes 't by solder oijothcr tastenin,f` ,if means, geuerallyapplied Aby dipping the lower header in a bath of solder or the like.

other wall S which is providedwilh apcrtures and sleeves 9 corresponding; in number and location to the apertures and sleeves of the 'wail 4. so that said ivalls may be placed in parallelism with the sleeves 9 registering;l with the sleeves G, so' that the sleeves 9 will represent a continuation of the sleeves 6 and ,75 In addition to the wall si, I provide ane,

afford a greater amount of material to be i connected to the tubes 7. The area of the" niterial cateringT into a joint yin the wall l of the. tubes 'l' is practically doubled with the ends ot the tubes more firmly braced and I anchored so thatthere cannot be any leak between the walls o'f'tlie tubes and the vWalls 4 and 8 ol" the lower header 1.

The wall 8 has marginal portions l0 which engage the marginal portions of the wall 4 and the inarginalportions'l are of greater area than the marginal portions of 'the wall 4 so that the marginal portions 10 may loe inherit, as at '11, to overlie the marginal portions of the` wall t;- -In other words, the'. marginal portions of the wall l are` ii'iclosed"r by the marginal .portions ot the wall 8 witlitbe sleeve portions of the; wall 8 in a. i

dillcreut plane tronrthe marginal portions l() of the, wall and the walls 4 and 8 will'be ,portions otjtlio ldouble wall fot thoheader composed of three plies of inalierlithi obvious that the edges ot the double wall are reinforced, that the wall ot tlie'lieader pos iesses a double strength and 2greater rigidity. and that the additional sleeves t) permit otthe ends of the tubes 'i' beingr positively attached tothe lower header 1.

The reference numeral 12 denotes an upper header or receptacle-which has a bottom y construction.

pThe headers 1 and 12 have the usual connections so that a cooling agent,- as water, may circulate through the headers and the, tubes 7, and said tubes are of cylindrical term having heat radiating or disseminating tins or members 18 thereon. The headers 1 and 12 and the' frames 17 may be connected together .by any suitable fastening means and is obvious that the headers 1 and 12 may have other shapes than those shown.

My invention particularly resides in the construction of the tube supporting walls, and While in the drawing, there is illustrated a preferred embodiment of my invention it iS to be understood that the construction is susceptible to such changes as fall within the 1. ln a radiator construction wherein top and bottom headers aril connected by tubes which establish communication between said headersz-means for connecting said tubi-s to said headers. said means comprising double walls, each having pressed out sleeves in which the ends ot' said tubesI are secured, said sleeves extending in the same direction.

2. Means for connecting tubes to radiator heads, as in claim 1 wherein said double walls are in spaced relation and so maintained by the sleeve ends ot' one wall ahnt.- ting the other wall.

As a new article o't manufacture. a sheet lnetal double Wall header havingr aliningr ontstruck tube holding material.

4. A new article ot manufacture as in claim 8. wherein the outstrucli tube holding' material has a sleeve formation projecting into the header.

In a radiator construction wherein top and bottom headers are connected by tubes which establish communication between said headers nieans for connecting said tubes to said headers, said means comprising spaced parallel sheet metal walls having contacting marginal portions connected together. said walls having outstruck portions extending' into said headers aml'connccted to said tubes.to maintain said tubes in spaced relation and attached to said walls.

In testimony whereof I atlix my signature in presence of two witnesses. i
